MACHINE FOR FINISHING HORSESHOE S.

SPECIFICATION forming art of Letters Patent No. 637,621, dated November 21, 1899.

Application filed February 28,1898, ri l-1 672,119. (No model.)

To all whom it may concern:

Be it known that I, OTTO KNIEP, a subject of the King of Prussia, German Emperor, re siding at Schonebeck, in the Kingdom of Prussia, Germany, have invented certain new and useful Improvements in Machines for Finishing Horseshoes, of which the following is a specification.

My invent-ion relates to a press for finishing horseshoes by preparing and attaching toecalks thereto and forming the clips thereon, which press, however, is intended to be used only on the ordinary horseshoe-blanks as commonly prepared-that is to say, bent around into the shape in which they are intended to be used, but not provided with toe-calksand clips.

My invention consists in the construction and combination of part-s, as hereinafter described and claimed.

In the accompanying drawings, Figure 1 is an end elevation of my improved press. Fig. 2 is a vertical section on the line a: w of Fig. 1. Fig. 3 is a cross-section on the line y y of Fig.

1. Fig. 4 is a partial front elevation of the I press as shown in Figs. 1, 2, and 3, difiering from it, however, in having means for the formation of the blanks for toe-calks instead of dies for forming the toe-calks and clips. Fig. 4? is a detail side view showingthe cooperating parts for cutting and shaping bars into toe-calks. Fig. 5 is a plan view of the parts shown in Fig. P. Fig. 6 is a side View showing the die of Figs. 4 and 5 detached. Fig. 7 i

is a detail view taken on the line .2 z of Fig. 6 and showing the action of the finger g on the bar. Fig. 8 is a section on the line m as of Fig. 7. Fig. 9 is a section on the line y y of Fig. 4:. Fig. 10 shows an implement for use in attaching the blank for the toe-call: to

the horseshoe. Fig. 11 is a modified form of the former and stamp for forming sharp edges on the toe-calk. Fig. 12 shows a sectional View of the same after the operation of the press and showing the horseshoe fully formed. Fig. 13 is a oross section of the horseshoe provided with a sharp edge, and Fig. 14 represents "a plan View of the bottom or face of the die.

a represents the driving-shaft, mounted in the frame it, which shaft, as shown, is provided with a pulley, to which motion may be communicated from any desirable source of power. In small presses this pulley may be replaced by a crank and handle and the press driven by hand. The shaft a carries a gearwheel I), which meshes with a larger gearwheelc,mounted onthecounter-shaftd. This counter-shafi carries two eccentrics e. and an eccentric f. Each of the eccentrics e acts on a knuckle-joint g h. The arms g are pivoted on a shaft 1', which acts as a fulcrum, and the arms h are pivotally connected to a crosshead Z, which is guided by vertical columns m m, which are rigidly mounted on the frame It of the machine. The eccentric f actuates a knuckle-joint n o, the arm n of which is pivoted upon the shaft 2' and the arm of which is pivoted to a stamp 12, which passes through the cross-head Z and is guided thereby.

On the under side of the cross-head Z is a U-shaped die q, which is secured in said cross-head by means of a set-screw 0', (see Figs. 1 and 2,) the opening of the U-shaped portion being opposite the stamp 19, as shown in Fig. 3. The stampp and the die q form the upper and movable part of the press. The lower stationary part of the press consists of a plate 5, supported on the frame 7:. and provided with a cavity of a size and shape suitable to accommodate the particular horseshoe t operated upon. The plate 5 is held in position upon the lower part 70 of the frame by means of, for example, four dowels a, and the arrangement of the parts being such that the stamp p and die (1 will come directly over the toe of the horseshoe. The plate 8 is provided with a cavity 71, (see Figs. 1 and 2,) which is just large enough to accommodate the clip when formed. The machine must be provided with as many plates s as there are different sizes of horseshoes to be operated upon.

The operation of the device so far described is as follows: A horseshoe t is placed in the cavity 8 and the toe-call: placed thereon by means of the implement shown in Fig. and hereinafter described. The machine is then put in operation, it being noted that either the shoe or calk, or both, should be heated. The movement of the counter-shaft d forces down the cross-head Z and holds the shoe firmly in position, with the die q holding the toe-calk in position and pressing it down against the shoe. The plunger 19 is then forced down. The U-shaped die q presses the calk against the shoe and welds it there'- to, while the plunger 19 swages down the front part of the calk and drives it into the cavity 4), thus, forming'the clip, so that at one downward movement of the press the toe-calk is; welded to the shoe and the clip formed.

Instead of the former q a former q may be inserted in the cross-head Z and held in place by the set-screw 0". shown in Fig. 4, and in an enlarged formand detached in Fig. 6. It is. provided with a knife (1 and a fingerq This finger g is adjustable by means of a set-screw g in an inclined slot qv in the head g of the former q. The knife g acts in'connection with the jaw w, (see Fig. 5,) which is adjustably secured on the lower part of the frame by means of a set-screw w. The knife g and the jaw w form two sides of a parallelogram, the other sides of which are the sides of the long' bar 1, which is to be cut into toe-calks. While the knife g is cutting ofi the bar 1 the finger g as shown in Figs. '7 and 8, swages down one side of the bar and forms a projection 2 to secure the blank to the shoe. i In Fig. 10 is shown in plan an implement which is to be used in securing the blanks for the toe-calks to the shoe in the following manner: The two rear dowels u are passed through holes 3 3 in the implement, a rectangular hole 4 receives the blank, and the movable arm 5 holds it securely in position. If it is desired to give the toe-calk a sharp edge S, (see Fig. 13,) the modifications shown in Figs. 11 and 12 are used. In this case instead of the former q a former 11 is used, provided with angles and an inclined face, as shown in Fig. 11. A downward movement of this former, together with the stamp 13, produces the shoe shown in Fig. 13.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-- 1. In a machine for making horseshoes, a

This former is stationary portion or anvil, com prisinga plate provided with a recess for the. horseshoe and a cavity. for the horseshoemlip, a movable portionvconsisting of a cross-head, and means for moving said cross-head'and stamp up and down so that as the die is forming the calk, the stamp will at the same time form the clip, substantially as described.

In a machine for making horseshoes, a supporting-frame, a plate onsaid frame provided with a recess for holding said horseshoe and with a cavity for the clip f said shoe, 'a cross-head provided with a die for forming the calk on said shoe, a stamp work- 'ing in said die for forming the clip on the counter shaft, eccentrics on said countershaft, a cross-head guided by said columns, knuckle-joints connected to said eccentrics, counter-shaft and cross-head, a stamp working in said cross-head, a forming-die secured to said cross-head, and an eccentric and knuckle-joint for driving said stamp up and down, but at difierent times from the movement of the cross-head, substantially as described.

In testimony'whereof I have signed my name to this specification in' the presence of two subscribing witnesses.

OTTO KNIEP.
